LIQUID-COOLER.

Specification of Letters Patent.

Patented Nov. 4, 1913.

Application filed April 4, 1918. Serial No.'758,842.

To all whom it may'concem Be it known that 1, JOHN PLoNY, a citizen ofthe United States, residing at Syracuse, in the county of Onondaga andState of New York, have invented certain new and useful Improvements inLiquid-Coolers, of which the .following is a specification.

This invention relates to improvements in liquid coolers, and theinvention relates particularly to that class of coolers in which beer orother liquids, after leaving the kegs or barrels, .is carried throughcoils which are submerged in ice-water. 7 I

The object of the invention is to provide a vitreous cooling device, totake the place of the usual metallic parts heretofore employed for thepurpose, 'wherein the beer or other liquid is carried or forced througha spirally arranged passage, the interior of .which is perfectly smooth,thereby permitting the ready :and complete cleansing of the li uidpassage.

A rther object is to provide a substantially transparent-cooling device,which permits of instant and accurate .inspection of the liquid passagesfor detecting discoloration or dirt.

A further object is to provide a suitable vitreoussupportand protectorforthe liquid coil or passage, for preventing injury to the same whenice is applied to and removed from zthe box orchest in which the .cooleris disposed, and .a further object is to ovide for combining the cooling.coil and t e pro-.

,teotor and support into one inseparable part, which is equipped withsimple and convenient .means for connecting the cooling coil tional viewof the vitreous .coil before the protecting envelop is ap lied thereto.Fig. 3 isatop planv-iewof 7 device. Fig. 4 is a horizontal section;showing the. method of combining the cooling coil and its envelop intoone part...

In the drawing, 2 represents the vertical portion of the ice box orchest of a beer or 9 complete cooling 1 other liquid cooler, and-3 isthe bottom portion of the same.

My improved cooler consists of a coil 4, which is preferably made ofglass tubing, which is first made in the form shown 1n 'Flg. 2, in whichthe convolutions are in close contact with each other.

5 and 6 represent respectively the to and bottom. terminals of the coil4, whic are preferably made of the same material as the coil, and arethreaded for receiving the gland-nuts ,7 which form parts of the usualunions 8.

9 represents a pipe which connects with the :terminal 5, and thenextends through the bottom 3 of the box, through which the beer or other"liquid 'is carried from the barnails or kegs .(not shown), which may belocated in any suitable place. 10 represents another metallic pipe,one-end of which connects with the top terminal 6 of the coil, while.the other end connects in any suit- .able manner with a faucet 11. Theparts 9,

10 and l'lmay follow any of the usual constructions.

The cooling coil 4, as described, is preferably made of glass, 'butitmay be made of any other suitable vitreous substance, for

providing :a transparent coil, having a clear and smooth interior forfacilitating the free passage of the liquid, as well as, the ready andproper cleansing of the .liqu'id passage.

The coil 4 being made of vitreous material,

which is more or .less fragile, requires suit able and adequatesupporting and'protecting means for warding off the 'jars and strainsincident to the use and care of cooling devices of the class, and tothis end, I provide an envelop or covering preferably consisting ofglass, or other vitreous materiail, the same as the coil 4, which com- 1prises a cylindrical outer layer 12, and a similar inner layer 13, thesaid protecting layers preferably being applied in the followmg manner:After the coils 3 are made up, as shown in Fig. 2, they are each placedin a mold or hollow form 14-14' (see Fig. 4,), in which the coil 4 isdisposedconcentrically, for providing a clear space, as 15, around thecoil. The next step is to insert a cylindrical core, as T6,concentrically within the coil in a manner to ,provide a clear space, as1 between the core and the coil. The next step consists of pouringmelted glass, or other similar vitreous .ma-

terial into the hollow spaces 15 and 17, for casting or forming theprotecting layers 12 and 13. After allowing the melted glass to cool andharden, the mold 14-44 and the core 16 may be removed. The coil 4 andits inner and outer supporting layers 13 and 12 will then be combinedinto one compact and inseparable part, as shown in Figs. 1 and 3. I

The complete device when removed from the mold is in the form of acylinder, having a comparatively large bore 18, which vice will betransparent, and any discoloration or dirt which gathers on the lnteriorsurface of the liquid passage may be readily detected, and as theinterior of the coil is intended to be smooth,like the outer surfaces ofthe envelop, all dirt and stains may be readily and effectually removed,by forcing any suitable cleaning agent through the coil. The outer andinner surfaces of the vitreous envelop may also be readily andeffectually cleaned without in any way disturbing the coil, and withoutrequiring the removal of the device, and the whole device is thereforerendered highly sanitary.

By making the complete cooling device in one part, as shown anddescribed, it is not liable to get out of order, and it will havesufiicient weight to hold itself in place without any other securingmeans. But in order to aid in holding the cooler in place, I haveprovided a number of feet 19, which are preferably formed integrallywith the outer protecting layer 12. These feet not only afford a broaderbase for supporting the cooler, but they also serve to hold the mainbody of the cooler a sufficient distance above the bottom 3 of the icebox, for permitting the proper flushing and draining of the box andcooler, without requiring the latter to be disconnected or removed.

After my improved coolers are made up and disposed in the ice-box, asdescribed, ice

and ice-water may be applied to the box, in the usual manner, and thebeer or other liquid which passes through the coils 4 will be cooledsubstantially the same as in the old styles of coolers, where metalliccoils only are employed.

The thickness of the vitreous envelop may crevices between the adjacentconvolutions of the coil, renders the complete device strong and capableof withstanding an ex tremely low temperature, and also rough handlingof the broken ice, as well as, the frequent tamping of the ice, withoutdanger of breaking or injuring the device.

My improved cooler is extremely simple, strong and compact, and can beproduced at a smaller cost than the wellknown block-tin coils. It can bemore readily and effectually cleaned, and when properly constructed andinstalled, it will outlast any of the metallic coolers known to me.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is-

1. A liquid cooler, comprising a vitreous coil having screw-threadedterminals for connecting with supply and discharge pipes, and a vitreousenvelop adhering to said coil for protecting and supporting the coil.

2, A liquid cooler, comprising a hollow vitreous cylinder open at itsopposite ends, and a tubular coil embedded in the walls of saidcylinder, the opposite ends of said coil provided with means forconnecting with pipes which conduct the liquid to and from said coil.

3. A cooler comprising a transparent vitreous coil adapted for carryingliquid to be cooled, and a transparent vitreous protector completelyenveloping said coil, said protector arranged in the form of a hollowcylinder capable of being submerged in and also filled with ice waterforcooling the liquid.

4.
